I'm currently out at a client site, but it's super bad reception here in the conference room they stuck us in. First of all, no 4G in colorado springs, so i disabled LTE, and hit CDMA in the network settings.
3G is near impossible inside, so i usually get 1X, and voice connection is next to impossible also.
So i noticed that from unplugging in the morning at 7:30am. at around 2pm, my battery was already down to 10%!
And i didn't even use it.
I did see from my battery usage, that Android system was ABOVE screen in power usage.
Anyone have the same issue?
I've had the same problem with EVERY phone ever, even non-smartphones have this problem. The lower the signal, the more the phone will scan for a good signal. If it has no service, it scans very frequently. If you're on a smartphone, it's even worse because then when the phone does get service, all the data apps attempt to use what little bandwidth you do have all at once. If you're in an area with poor coverage, put your phone into download mode or disable the data connection. Nothing short of putting a network extender or new tower will solve this.
Yes, but this is typical of most phones really. Searching for a signal, acquiring it, losing it, etc, uses a lot of battery. You just have to disable data. If there is wifi available, then use that, if not, just have to wait until you go outside. I have no reception in my building at work, if I leave data on, my battery is dead in a couple hours, on wifi I can go all day
Yes and my phone got very hot in my pocket at the time as well.

I have this issue at work. I get anwhere from 10-15% battery drain an hour. I have determined that it is NOT because of the data signal though becuase I can turn that off and still get about the same excessive drain. It appears to be because of the voice signal. It varies anywhere from -85dm to -115dbm and is constantly changing. When I get outside of work environment, everthing is fine again and battery usage returns to normal. My Droid X did not have this issue.
-115db? How do you have signal at that rating? lol. Phone gets to about 1 bar when it reaches 101 for me.
I have the same issue in my office. I just barely get voice/text service. My solution is to turn off mobile data and plug my phone in to balance out the battery drain from the weak signal. I know it is bad to have my phone plugged in all of the time but it is better to be able to have sms and not have a dead phone when I am done at work.

Yeah. Tell me about it. I am using Mobile Signal Widget to measure this. When It gets that bad, a little android face appears in the widget and it is crying.
YES! easily drains 10-15% an hour at a local pub that has 1 bar of signal.
It makes perfect sense... Your phone is fighting hard for that signal.

I drive 50+ miles to get to work and I always notice it drains a lot during my commute even when not used. I figured it was because of all the cell site swaps and searches bc I'm sure there's some spotty areas.

Same experience. Dropped to 5% in 9 hours yesterday when I forgot to turn off data while at work. Today, I'm still at 75% after 9 hours with data off.
Juice defender solved this on my fascinate. It turned data on only once every 30 minutes. But, I can't get it to turn my data back on with this phone.
I really wish data signal aggressiveness was managed better by the operating system. It could be a real boon to the average battery life. Perhaps a smart developer could come up with some sort of "conservative" governor for 3g/4g connections. Rather than increasing power draw, it could just "sleep" until a stronger signal is detected... Imnuts? Is this even possible or just a pipedream?

I can't reach my dad on his cell phone while at the pentagon for obvious reasons. He has to turn his phone off during the day or it'll die in a few short hours, as a previous poster mentioned searching for a signal is a huge battery drain.
Strange. I did not have this problem with my OG Doid or Droid X in the same environment. Maybe the Moto phones simply have a better radio than the Charge.
Yeah for some reason, the samsung radio are junk. I have my Droid Charge (personal) and an Lg phone (business) and the lg blows the sammy out of the water. Now i am in 3g fringe (forget about 4g), and the sammy loses data all together while my lg still has the signal. I hate when i am trying to search for something on the charge and it says connection failed or network unavailable retry. Even when i call verizon, they all have me do a reset and stuff, and nothing works. The best answer i get is that iam in a 3g fringe area. When i tell them that my lg works and still has signal, all i get is silence or hmmmmmm. Gota love it. Yes they exchanged the phone with a new one and it still does the same thing. Forget about battery life. I actually carry 3 batteries with me and on a good day i only use 2 but usually it is 3. Before anyone says use wifi, unfortunatly we do not have free wifi where i work. anyway that should not be the answer to this problem. We are paying for a service that i can barely use.

I went through the whole VZW customer service thing both on the phone and in person. They weren't much help but they gave me a brand new phone and it does the same thing. Then there were a lot of suggstions on different forums suggesting apps killers, turning data off, turing on 3g only data, rooting, trying different ROMs, battery clalibration, etc. None of this helps. The kind of drain I am seeing goes way beyond any benefits I would see out of any of these things. For example, I am at work now. When I left the house, it takes about 15 minutes for me to get to work. The rest of the time I have been inside my work building. I have been on battery for 2 hours & 24 minutes and I am at 76% already. Thats >10% drain per hour. When I am outside the building it is more like 3-5%. VZW customer service never suggested this as a problem. They DID suggest that 4g uses more battery but that is not the problem. I have proved that time and again by simply turning data off.
Hmm..sounds like a bad phone..I am in a fringe area at work and it definitely kills by battery faster but..it's only like 8% and hour so I still get 10 hrs a day or so...in a bad area. In a good 4 G area..I will get 24 hrs or so out of the phone.

Wow, that is the complete opposite of my experience. I've never had good signal with any LG phone - from flip phones to smartphones. Samsungs in my experience are middle of the road - not great, but not bad either. Motorolas usually do well, but there are certainly exceptions. HTC seems to be fairly good, but again, there are exceptions. Oh, and I did have one Audiovox phone on VZW, and it was garbage.

It seems to all come down to how good of a connection area you are in. It seems that people in low or bad connection areas experience way faster battery drain on ICS, but if you are in a strong signal strength area the battery actually seems better. Of course, this is just what I have noticed because I work in a low signal strength area (way faster battery drain), but I live in a good signal strength area (extremely good battery life). I've tried several different modems and although the rait of drain varies, it still holds true. Everbody's results may vary. I am hoping when "network switching" is introduced to ICS that it will help solve the problem.

Lower the signal more power is needed by modem to hold connection; this is how all modes work. But I do work in the area with very week LTE or even week 4G and I still get better battery life then with GB. It took few days to get batter battery life.

Good for you, glad it's working well for you.
I went back to GB earlier due to my dialer being extremely laggy, but the market place wouldn't allow me to download from the marketplace. It would go through the motions like it was going to download but then it would do nothing . Suggestions on let this?
I went back to the ICS leak and then installed the Super lite version and my phone is running amazing, but would like to know any suggestions as I may still go back to gb.

OK, so my wife and I both have GS3's through T-Mobile and our batteries last very long. I'm a heavy user and get a fully day while my wife is a light user and easily get's two days. My Mom on the other hand has her GS3 through Verizon and her battery is dying in roughly half a day. She is not a heavy user at all. In fact, her old Droid 2 would last longer than her GS3 which really has her frustrated.
I think it may be due to the fact she doesn't get a good 4G signal at work and at home. In fact, she gets 1 bar at work if she's lucky. She also said the phone is constantly bouncing back and forth between 3G and 4G while at work. She took it to Verizon today and they swapped SIM cards to be sure that wasn't the problem. Obviously that didn't work because I'm posting here. I will see her on Thursday and she want's me to look at her phone.
Do you guy's think this is most likely the reason as to why her battery is draining so fast? Also, if it is. Would there be a way I can show her how to disable 4G so her battery lasts longer?
It's most likely 3G and 4G switching back and forth or a rogue app. For to turn off the 4G it can't be done without rooting I'm pretty sure.
No, it's because you have task running. I had the same thing happen to me. If you exit an application by pressing home, the program will continue to run in the background. I had gallery take up 38% of my battery life. If you press the back button, it will FC the application.
Good bye HTC Rezound, hello Galaxy S3!

I'm on verizon as well and I find that my battery dies extremely fast. Full charge in the morning and by bedtime its just about dead, that's with moderate use. Some things that I have found to help is I generally keep bluetooth, and gps off unless I need either. I keep power saving mode on, and really minimized what Sync's through my accounts.
It's not exactly the answer you were looking for but it should help you until a more long term solution can be figured out.
Does anyone know how to turn 4G off?

Low tower signal will kill the battery very fast. Frustratingly fast. I have Verizon GS3, have very low signal at work, and I burn 8% battery per hour when phone is idle. With almost no use, my battery is down to 30% by time I go home.
At home I have good tower signal and my battery drops very slow in idle, maybe 1% per hour. At both work and home I have WiFi connected and set to keep WiFi on during sleep always. Therefore I don't think it's data traffic / sync causing the issue. Instead its hyperactive radio hardware or firmware killing itself as it constantly finds/loses tower connection. The only thing I've been able to find to reduce the drain is going into airplane mode... which is obviously a terrible option.
Hope Samsung can improve this self devouring nature in the future!

go to the playstore and download "phone info" open it and go to device information
Swith the " lte/cdma/evdo" into cdma auto (PRL)
I also turn off 4g at work due to weak signal
VERIZON GALAXY S 3
I believe its a signal search at where she spends most of her time. At my work the signal is very bad and the phone goes from 100% to 20% in 10 hours without even touching the phone. Now I turn on airplane mode and it never drops the battery.
She can disable the data and find out how much that would save her
First make sure it's not a rogue app by going into Settings -> Battery, your top 2 battery usages should be Screen and Cell Standby. As long as you don't have some random app eating away at your battery then it's definitely signal strength related. Does she have Wi-Fi available at work? If so make sure she connects to it. I have a Verizon S3 and the battery life on this phone is better than any Android phone I've ever owned (and I've had a lot). I leave GPS and Bluetooth on all day and can easily get a full day with mid to heavy usage. The biggest thing would be to get her on Wi-Fi if available. This will stop the phone from constantly trying to poll data off a poor signal and significantly increase battery life. If no Wi-Fi available, then the above post would come into play, Phone Info app and switch into cdma to keep it locked into 3g will help, but only if there's a decent 3g signal. If the 3g signal is weak also, then you're not going to help anything, and she will just need to remember to turn data sync off while she's at work.

Try switching batteries to see if she has a defective battery. If thats not the case, then make Verizon give her a replacement S3.
Add me to the list of people who think its the signal search in low service areas.. I disabled 4G with the Phone Info app and my phone lasted way longer than before..
Since you pointed out she has a low signal, I wouldn't be surprised if that's the culprit..

Ahhh so it wasn't the battery itself?
When you got a replacement S3, did you go back to the same store where you had originally purchased them from or tried a different store?
I disabled 4G today at work with my stinky cell signal and my battery nose dived like usual. Therefore, if you have no signal, 3G/4G doesn't seem to matter. The radio hardware will still destroy itself happily.
Anyone know of a widget my Mom could use to disable data completely while she is at work?

Pull the task drawer down and uncheck mobile data. Why do you need a widget?
You might have a system process called "gsiff_daemon" draining the battery. I have that problem and others have reported that process has been draining their battery as well. Or it could be other have mentioned already, signal switching, rogue programs, etc.
Today at work I ran with mobile data off. I still had a really bad battery drain. Therefore the voice 3 g radio must be responsible. Not much we can do about that unless a new firmware comes out.

There's also an option in the settings>developer options to restrict how many processes are running in the background, and to kill an app after leaving it. The only problem I've noticed with the second option is that the fb app won't allow you to post a status, I think because it causes it to start a new activity, which kills the main fb activity when you leave it. But limiting the background stuff seems to have saved some more juice on top of only using 3g.

Hey not sure if im even putting this in the right thread but im very new to rom and kernel flashing etc
Im running CleanRom 5.0 and Beastmode 4.3 Kernel
My battery life right now is 30% after 8 hours...what am i doing wrong both the rom and kernel have allegedly good battery life...i recently flashed both like 2 days ago...am i supposed to let the kernel and rom calibrate etc before i freak out about the poor battery?
My screen is using abt 60%
voice 20%
standby 5
whats app 4% phone idle 4%...not sure what other info to provide but can anyone help me make modifications for better battery life
im using kernel tuner i tried governor: badass, wheatley, intellidemand..my screen brightness is veryy low i took it off auto because i felt it was sucking it even faster. I dont think im overclocking...random apps like youtube, facebook etc are running in the background is this a huge problem?
someone pls help!
thanks
What is your screen on time?
60% brightness isnt "low" by any means, I usually leave mine on 40%. You made a good choice to take the phone off auto brightness.
Personally I got really bad battery life with beastmode. I now run flar2's experimental 1.5 GHz kernel and couldn't be happier.
Radios also have a significant impact on battery life. The 2.29 radio + ril has worked best for me with battery life.

Think he means screen is using 60% on the battery usage stats, not screen brightness.
60% is fairly high. I think he just has the screen on a lot. Brightness may also be a factor. Only about 4-5 hours if screen-on time is to be expected on low brightness.

Battery life
Hey guys, I've recently bought a AT&T HTC One X. This is my first smartphone, and it is fully stocked, locked bootloader and no root, android 4.0.4 and software version 2.20.502.7, really like the phone. However, I am not really impressed with the battery life. I would usually charge it over night for around 8 hours, take it off in the morning at around 08:00, take it to school, casually check facebook/gmail, maybe watch one or two videos and by the time I get home at around 15:30, the battery would be at around 15%. I was wondering whether this is normal and if there is any point of my rooting the device and flashing any custom roms?
I have disabled all the AT&T bloatware, decreased my screen brightness to around 25%, no live wallpapers, disabled auto syncing, wifi and mobile data mobile switched on only when I use it, only have a weather/clock widget and a couple of games. So I have been researching about rooting and customer roms for about a month now, and found out that some members have amazing battery life times with Cleanroms and custom kernels, so I was wondering whether the latest 5.1 Cleanrom with a Beastmode kernel 4.4 would cause any damage to my phone and whether any of you guys are using it?
Thanks for your time!

Are you using LTE? I found that my battery would drain very quickly when set to use LTE, even if I'm on wifi. I guess the LTE towers were further away or something because my signal would drop really low. I leave my phone on 4g for the most part now, only switching to LTE when I really need it, and I can get two days of battery with light usage. I've only recently flashed CleanROM so I would expect it to get better, but it's too early to tell. I've only got 22 minutes of screen time, but my phone has been on for 9 hours and it's at 85%.

Wow, that sounds good, even with that much screen time the standby is much better than on my device. Sorry I forgot to mention, I live in the UK and LTE or 4G is only available in major cities. However, my phone is AT&T and is sim-unlocked, and I get the '4G' mark on the top of the screen, therefore I think it might be the HSPA+ that is available in my area, which I rarely use anyway.
Is it the stock kernel that you have flashed with the rom?
Thanks.

Just because that person got a particular battery life by toggling off LTE, don't assume that you will get the same results. Battery life often tends to be very reception and location specific.
I leave LTE on 24/7 (as well as WiFi, and brightness on 40%), and can get close to 48 hours on a charge with low usage.
Also, bear in mind that you can't toggle LTE off on AT&T stock ROMs.

That's correct, on stock AT&T ROMs, the "4G" icon means HSPA+. If its on LTE, it will say "4G LTE".
My guess is that you are just having reception issues. Flashing ROMs and kernels may get you slight improvements in battery. But don't expect it to make a huge difference, or you will likely be disappointed. A different radio may also help.

Just because that person got a particular battery life by toggling off LTE, don't assume that you will get the same results. Battery life often tends to be very reception and location specific.
I leave LTE on 24/7 (as well as WiFi, and brightness on 40%), and can get close to 48 hours on a charge with low usage.
Also, bear in mind that you can't toggle LTE off on AT&T stock ROMs.

Thank you, I will have this in mind. I was wondering whether it was due to reception or was it just the batter malfunctioning. In your opinion, would it be better to wait for the Jelly Bean update and see whether the battery life improves?
Thanks.
I have to say there are lots of thing that went backwards in the Jelly Bean update, but battery life seems to be worst. With all location services off, all maps location repoting/history off, the idle drain in low cell signal areas is terrible. Way worse than ICS.
I don't see any abnormal processor usage or wake locks. I think this means the radio is to blame.
Damn am I tired of Samsung/Android updates adding new features but making some things worse. I tried to like Android and defend it. I can't do it anymore. It's sloppy and rushed. I hate it now.
I am running stock deodex BLK3 and have had no problems with battery drain. Actually I am getting better than I had on ICS.
Only things done to it are kinda crap mods and removing stock applications. I have GPS on about 50% of the day and hardly ever use wifi.
I'm on cleanrom 5.5.1 and battery life is very good I can easily make it through the day

On on stock with Apex launcher. I'm a moderate user (browser, calls etc) and I get 24 hours and still at 30%+ Most of the time I'm on wifi as our building does not have great interior reception.
IP, download Carat app and see what is draining the battery. I assume you already used BetterBatteryStats and there were no wakelocks? Check if there are any apps that are refreshing at short intervals. The battery drain issue should not be that drastic. From my experience, I was completely stock ICS (bloat and all) until the JB update. Right now I am unlocked, rooted and debloated but still stock - and battery life is only slightly worse (VZW remote diagnostics were also disabled). If nothing else works, then wipe/ODIN to stock and see if things are different then.

Lol don't blame Android. Samsung is the one who puts so much stuff on top of android. If you want a stock android go buy a nexus.. Not a modified version of Android

You are correct, most of my anger should be directed at Samsung. I'm very curious if Nexus devices are free from this eternal flakyness.

I use slim bean and get very good battery life. I spend 8 hours at work with no reception and I will get 34 hours out of my phone if I dont put airplane on and 42 if I do.

I came from a galaxy nexus. The battery life was bad, really slow updates, and signal sucked (till jellybean)
I lost about 30m - 1hr of screen on time going to 4.1, but 4.2 seems to have it all worked out again. Hopefully Verizon allows us to have 4.2.

I've gotten better battery better signal faster GPS on clean Rom(jb)

I think each battery usage is different. Making your screen turn off quicker will save battery, turning off GPS will help too. I would like to know if WiFi or 4G:LTE uses more battery because with an unlimited data plan I can work with it a lot easier one way or the other.
Anybody done any research or have an inkling for one or the other?
Wi-Fi uses less power 4G uses more power, that's a fact.

I had terrible batt life after updating to JB. On ICS i would get 1% loss each hour when idle, right after the update it was more like 10% each hour. I ended up reading thru tons of posts not only for sgs3 but other phones updating to JB and having batt problems. So i factory reset and formated the sd card then put my files back on it. Then i finally found a post where it was stated that if you have a lot of media either on phone or sd the system will have to index each file, for thumbnails, quicker pinch zoom in gallery etc. That kept my phone awake and killing the battery for a good 12+ hours after the update. Today it finally ended. I am now 24 hours off the charger with 89% batt remaining, making it about .4% discharge per hour. I know this wont solve everyone's problems with the battery drain but maybe it will help some. GL!
I see a big difference for me with the battery between ICS and Jellybean rom. I was on Bean's custom stock build 15 originally and with medium - med heavy use, I see about 15-20% remaining battery after 10+ hours of use. With the new Bean's jelly rom b7, I need to charge before 10 hours with the type of same usage. This morning, I saw a 12% drain in 20 minutes for checking facebook/instagram and some email.

That's not true. If you have good LTE coverage it uses less power than WiFi. I have confirmed this checking power consumption with Battery Monitor Widget Pro. I'm losing ~22 mV every 10 minutes with WiFi turned off and pretty good LTE coverage (-100 dBm) and ~28 mV with WiFi on. When there is poor coverage WiFi will be better choice of course.

I will keep that in mind. Thanks
With Wi-Fi the signal is right there no sharing with millions of ppl no searching for signal, with 4g you'll use more power.I've done test with both and my 4g is great but still Wi-Fi uses less examples 4g great signal maybe 12-18hrs battery moderate use...Wi-Fi 1 day 9 hrs same usage.you do the math

My Jelly Bean battery issues are very tied to cell signal level. At home today, with good signal (LTE -100 dbm), I see no idle drain issues with JB. Its just like ICS. However, this last week at work with poor signal (LTE -112 dbm), with JB I had terrible idle drain. In that exact same setting ICS had no issues.
I have a feeling the new radio is doing some hyper spastic searching for better towers now around -110 dbm, where it didnt used to. If my woes at work keep up I'll flash back to ICS radio.
I've gotten great battery also on ics whether on 4g or Wi-Fi that time really didn't matter,I loved the hd radio.but on jb the lk3 is ok I do get faster gps lock.
